The purpose of this thesis was to investigate the information needs and information-seeking behavior of the Buddhist nuns in Taiwan. The study also explored differences among Buddhist nuns (with different characteristics) in the use of libraries and Internet resources. Prior to conducting the study, a questionnaire was designed and developed based on analysis of literature and practical situation. The questionnaires were distributed to Buddhist nuns in different nunneries and monasteries to gather needed information. From the 119 returned questionnaires, only 100 were valid. They were analyzed by using SPSS for Windows. The findings of the study indicate that the teaching-related information is the most frequently used information type for the Buddhist nuns. The types of information needed varied significantly when the ages of Buddhist nuns and years of being nuns were different (p<0.05). Buddhist nuns reacted that they did not want to spend much time in using particular information channel. For them, the library was the most frequently used and satisfied information provider. The study indicates that the Buddhist library was used frequently by the Buddhist nun, because there were many Buddhist materials to support the Buddhist nuns in studying. Circulation Service in Buddhist library was used frequently. Many Buddhist Nuns declared they had difficulties in finding needed information when they are using the Buddhist library. They expected to have more materials to support their information need. 80% of respondents had experience in using Internet, and the use of Internet varied significantly when their identities were different (p<0.05). Many Buddhist nuns don’t know how to use library services in Internet. The main purpose of using Internet was to obtain "The Buddhist-related information or activities". There was a significant difference for the purpose of using Internet between the nuns who were studying and the nuns who were working. One of major purpose of this study was to explore the differences of the information need, information-seeking behavior, use of library, and use of Internet among Buddhist Nuns with different identities. The findings indicate that there were no significant differences in information need and information-seeking behavior for different identities. There was a significant difference in the item "things that they hope to improve in the Buddhist library" among different identities (significant differences in studying nuns vs. working nuns and self-cultivation nuns vs. working). There was also a significant difference in the item "Internet experience", " place for using Internet", and "purpose for using Internet" among different identities (significant difference in studying nuns vs. working nuns). Several suggestions were provided in the final section of the study: (1)It is necessary to attend to continuing education for the Buddhist nuns;(2)It’s important to train the professional librarian of the Buddhist library;(3)It will be helpful to establish collection appropriate to the Buddhist nuns;(4)It is important to plan the appreciable library use instruction;(5)Provide the appreciable library service;(6)Provide the program about Internet reso
